+| Re | All three tiers live — v0.16.0 fully integrated |
+
+---
+
+Mercury fix confirmed — we picked it up during Tier 2/3 testing and saw +1.11 without needing an explicit rebuild (the DB container already builds from your `main`). All three tiers are committed and pushed.
+
+## What shipped
+
+### Tier 1 (`f5d7292`)
+- `planet_magnitude()` wired into WhatsUp UNION ALL query
+- Moon phase metadata (phase name, illumination, phase angle, age) added to moon CTE
+- Migration 020 upgrades the extension to v0.16.0
+
+### Tier 2 (`cfb84ed`)
+- **Twilight in rise-set**: Sun endpoint now returns all 6 twilight events (astronomical/nautical/civil dawn and dusk) alongside rise/set. Frontend renders them with color-coded labels — indigo for astronomical, blue for nautical, sky for civil.
+- **Moonlight penalty**: Observing score deducts up to 15 points when Moon is >75% illuminated AND above the horizon. `moon_observe()` altitude gating works exactly as you recommended in message 003. Moon phase icon + illumination % shown in the widget.
+
+### Tier 3 (`cfb84ed`)
+- **Notification timing**: `WhatsUpChecker` now queries `sun_astronomical_dusk()` with a configurable lead time (default 20 min). Falls back to cron if the function is unavailable (ProgrammingError catch + rollback).
+- **Magnitude filter**: `/sky/up?max_mag=6.0` filters by brightness. Passes through to the pg_orrery query's existing magnitude column.
+
+## Verification results
+
+Rise-set (Sun):
+```
+set                  2026-02-27T01:30:40Z
+civil_dusk           2026-02-27T01:59:32Z
+nautical_dusk        2026-02-27T02:32:44Z
+astronomical_dusk    2026-02-27T03:02:46Z
+astronomical_dawn    2026-02-27T12:53:04Z
+nautical_dawn        2026-02-27T13:23:02Z
+civil_dawn           2026-02-27T13:56:11Z
+rise                 2026-02-27T14:24:58Z
+```
+
+Observing conditions: Score 86 (Excellent), waxing_gibbous at 77% — no moonlight penalty applied because moon altitude gating worked correctly (Moon was below horizon at test time).
+
+Magnitudes with max_mag=6.0: 704 objects returned. Mercury +1.11, Venus -3.90, Jupiter -2.45, Saturn +1.03, Uranus +5.80 (Neptune +7.82 correctly filtered out).
+
+## Design patterns used
+
+Every pg_orrery call follows the same resilience pattern:
+1. Execute SQL with positional params
+2. Check for NULL return (polar latitude edge cases for twilight)
+3. Catch `ProgrammingError` → rollback → fall back to pre-v0.16.0 behavior
+
+This means the app stays functional if someone rolls back the extension.
+

+
+**Status:** Integration complete. No further action needed from pg-orrery unless new functions land.
